CallVisor Adjunct-Switch Applications Interface (ASAI) links Communication Manager and adjunct applications. The interface allows adjunct applications to access switching features and supply routing information to Communication Manager. CallVisor ASAI improves Automatic Call Distribution (ACD) agents’ call handling efficiency by allowing an adjunct to monitor, initiate, control, and terminate calls on the Avaya Server. The CallVisor ASAI interface can be used for Inbound Call Management (ICM), Outbound Call Management (OCM), and office automation or messaging applications.

CallVisor ASAI is supported by two transport types. These are:

CallVisor ASAI messages and procedures are based on the ITU-T Q.932 international standard for supplementary services. The Q.932 Facility Information Element (FIE) carries the CallVisor ASAI requests and responses across the interface. An application program can access CallVisor ASAI services by supporting the ASAI protocol or by using a third-party vendor application programming interface (API).
